Abstract
The utility model provides a double-purpose drilling tool and belongs to the field of machining tools. The double-purpose drilling tool comprises a cutter rod and cutter heads, wherein the cutter heads are arranged on the cutter rod which is in a cylindrical shape, and the cutter heads are distributed on the cutter rod with the center point of the cutter rod as a center in an annular mode. The two cutter heads are arranged on the cutter rod up and down in a concentric mode. The lower cutter head is an expansion cutter, and the upper cutter head is a reamer. The length and the diameter of the reamer are both larger than those of the expansion cutter. The double-purpose drilling tool is reasonable in structural design, capable of carrying out rough machining and fine machining of boring operations, and high in machining speed and efficiency, and the expansion cutter and the reamer are arranged on the cutter rod. Since the cutter tool does not need replacing, positioning deviation can not occur, machining is accurate, and product qualified rate is high.
Description
Technical field
The utility model relates to a kind of drilling tool, relates in particular to a kind of dual-purpose type drilling tool, mainly is applicable to the processing in hole.
Background technology
At present, general boring work needs three cutter: 1. knife edge, be used for the position of location drilling, and 2. expand cutter, be used for reaming, 3, reamer, for the fine finishining to reaming.Need to increase the man-hour of single-piece with changing cutter No. three times for the processing of a workpiece, and if occur the school in the process of tool changing and defend inaccurately, just produce easily error, make boring work not reach requirement, produce waste product, wasted resource, increased production cost.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of precision machining, need not the dual-purpose drilling tool of frequent cutter head.
Technical problem to be solved in the utility model realizes by the following technical solutions:
A kind of dual-purpose drilling tool, comprise knife bar and cutter head, described knife bar is provided with cutter head, described knife bar is cylindrical, described cutter head take the central point of knife bar as center of circle annular spread on knife bar, described cutter head is provided with two, and described cutter head is arranged on the knife bar one on the other, and two cutter heads that arrange one on the other are concentric circle.
The cutter head of described below is for expanding cutter, and the cutter head of top is reamer; The length of reamer and diameter are all greater than the length and the diameter that expand cutter.
The cutter tooth of described cutter head is straight sword.
The cutter tooth of described cutter head is set to 6.
The beneficial effects of the utility model are: the utility model reasonable in design, expand cutter and reamer in the knife bar design, can carry out roughing and fine finishining to boring work simultaneously, process velocity is fast, efficient is high, owing to need not change cutter, therefore can not have deviations, so precision machining, product percent of pass is high.
Description of drawings
Fig. 1 is a kind of dual-purpose drilling tool structure schematic diagram of the utility model;
Fig. 2 is the utility model cutter head structure schematic diagram.
Wherein: the 1-knife bar; The 2-cutter head; The 3-cutter tooth.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1 and Figure 2, a kind of dual-purpose drilling tool, comprise knife bar 1 and cutter head 2, knife bar 1 is provided with cutter head 2, knife bar 1 is cylindrical, cutter head 2 take the central point of knife bar 1 as center of circle annular spread on knife bar 1, cutter head 2 is provided with two, cutter head 2 is arranged on the knife bar 1 one on the other, and two cutter heads 2 that arrange one on the other are concentric circle, and the cutter head 2 of below is for expanding cutter, the cutter head 2 of top is reamer, all greater than the length and the diameter that expand cutter, the cutter tooth 3 of cutter head 2 is straight sword for the length of reamer and diameter, and the cutter tooth 3 of cutter head 2 is set to 6.
The utility model is to realize like this, roughing is carried out in 2 pairs of holes of cutter head less by the below diameter and that length is short, and then fine finishining is carried out in large by the top diameter, that length is long 2 pairs of holes of cutter head, so just avoided changing the trouble of cutter, simultaneously owing to the error of changing the cutter generation does not exist yet.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
